a. Explanation Give info: In a journal it was discussed about the quality of carbon-foam rings which are used in nuclear missile housings and these are produced by combination of ‘mixing ingredients oven curing, carving’. The dependent variable is number of black streaks in manufactured ring ( y ) and the independent variables are revolutions per minute ( x 1 ) , cutting blade position ( x 2 ) . Calculation: The dependent variable is number of black streaks in manufactured ring ( y ) and the independent variables are revolutions per minute ( x 1 ) , cutting blade position ( x 2 ) . The interaction model for the two independent variables is, E ( y ) = β 0 + β 1 x 1 + β 2 x 2 + β 3 x 1 x 2 Here, β 0 is the intercept of the regression model when the independent variables are zero b. To determine What does the interaction term would be in this model.

Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. The article "An Intelligent Insole for Diabetic Patients with the Loss of Protective Sensation" (Kimberly Anderson, M.S. Thesis, Colorado School of Mines), reports measurements of temperatures, in °F, of both feet for 181 diabetic patients. The results are presented in the following table. Left Foot Right Foot 80 80 85 85 75 80 88 86 89 87 87 82 78 78 88 89 89 90 76 81 89 86 87 82 78 78 80 81 87 82 86 85 76 80 88 89 Construct a scatterplot of the right foot temperature (y) versus the left foot temperature (x). Verify that a linear model is appropriate. b. Compute the least-squares line for predicting the right foot temperature from the left foot temperature. If the left foot temperatures of two patients differ by 2 degrees, by how much would you predict their right foot temperatures to differ? Predict the right foot temperature for a patient whose left…

You have come across some evidence that the average efficiency of phovotaic cells made from Monocrystalline Silicon is less than that of Multijunction Gallium Arsenide cells. So, you request a sample of each from the manufacturer to test. How would you go about gaining insight whether (or not) the Multijunction Gallium Arsenide cells are more efficient than the Monocrystalline Silicon? Be very specific about your sample and design.
